Definitions
- DE 10 2011 005 819 B4 discloses such a housing which is in the form of a roller-blind cassette and is provided for a protective device in the form of a roller blind for a motor-vehicle interior.
- the roller blind has a rotatably mounted roller-blind shaft and a flexible sheet-like structure in the form of a roller-blind web, which is retained on the roller-blind shaft such that it can be wound up thereon and unwound therefrom.
- the roller-blind cassette has a housing profile with an angular profile cross section provided with a slot. The profile cross section bounds an accommodating space, in which the roller-blind shaft and the roller-blind web—in the wound-up state in any case—are accommodated.
- the roller-blind web can be withdrawn from the roller-blind shaft, out of the housing profile, through a profile opening.
- the profile opening is formed by said slot.
- the housing profile is formed from a panel-like semifinished product which is manufactured from plastic and—in a ready-for-use state—is angled along at least one predetermined folding line, which extends in the longitudinal direction, in order for the angular profile cross section to be formed.
- the solution according to the invention makes it possible to dispense, in particular, with high-outlay metal-forming techniques for the purpose of forming the angular profile cross section.
- the housing profile is formed from a semifinished product which is manufactured from plastic and, in order for the housing profile to be formed, is merely angled along at least one longitudinally extending predetermined folding line.
- the semifinished product is in the form of an at least essentially planar panel.
- the at least one predetermined folding line is arranged in a corner region of the housing profile.
- the angular profile cross section preferably has a C-shaped or U-shaped basic shape, wherein the basic shape can be provided with further profile portions. If such a basic shape is provided, the semifinished product can be angled along at least two predetermined folding lines.
- the profile opening can be subsequently separated out of the housing profile and/or formed between semifinished-product ends which are angled in relation to one another.
- the profile opening preferably extends longitudinally and is in the form of a gap, slot or the like.
- the profile opening preferably extends over an entire length of the housing profile.
- the at least one predetermined folding line is prefabricated on the semifinished product.
- the at least one Predetermined folding line it is possible for the at least one Predetermined folding line to be separated out of the panel-like semifinished product by virtue of material being removed or to be formed in the semifinished product without material being removed.
- the at least one predetermined folding line extends longitudinally in a continuous manner preferably over an entire length of the semifinished product—and therefore over an entire length of the housing profile.
- the at least one predetermined folding line can be interrupted in some regions.
- the at least one predetermined folding line is introduced, preferably in the form of a depression, into a flat side of the semifinished product.
- the at least one predetermined folding line can be in the form of a groove, of a channel, of an indentation or the like. Since the at least one predetermined folding line is already prefabricated on the semifinished product, manufacturing of the housing can be simplified further.
- the profile opening is formed between ends of the semifinished product which are angled in relation to one another.
- This configuration of the invention means that an operation in which the profile opening is subsequently separated out of the housing profile can be dispensed with. This achieves further-simplified manufacturing of the housing. Accordingly, in the case of this configuration of the invention, the profile opening is formed solely by virtue of the semifinished product being angled along the at least one predetermined folding line.
- a damping layer which is manufactured from a sound-damping material, preferably a felt, is provided and arranged on the inside. “On the inside” means that the damping layer forms an inner surface of the housing profile, said inner surface being directed toward the accommodating space.
- the damping layer avoids a build-up of noise in the interior of the housing. Such a build-up of noise can arise—in the installed state of the protective device—as a result of the winding shaft or the flexible sheet-like structure striking against the housing profile from the inside as a result of the driving conditions. Since the damping layer is already provided in the layered construction of the semifinished product, it is possible to dispense with any subsequent inner coating of the housing profile and manufacturing outlay can therefore be reduced.
- the panel-like semifinished product is produced by means of compression molding.
- Compression molding is known, in principle, as a method for producing flat or slightly curved components from plastic in the field of plastics technology and engineering. Producing the semifinished product by means of compression molding has proved to be particularly advantageous here, in particular if the semifinished product has a layered construction with a plurality of different material layers. Compression molding is involved in a particularly advantageous configuration of the invention.
- the invention also relates to a method for producing a housing according to the above description.
- a panel-like semifinished product which is manufactured from plastic is angled along at least one predetermined folding line, which extends in the longitudinal direction.
- This allows the profile of the housing to be manufactured in a particularly straightforward manner.
- high-outlay metal machining or the like can be dispensed with.
- the panel-like semifinished product is preferably angled a number of times along a respective predetermined folding line. This allows for example a C-shaped, U-shaped or rectangular basic shape of the angular profile cross section to be formed in a particularly straightforward manner.
- the panel-like semifinished product can have, for example, a layered construction, with a plurality of different material layers, according to the above description.
- the method comprises a step: the semifinished product is heated.
- the operation of heating the semifinished product renders the latter more flexible than when it is in a cold state, and it can therefore be angled more easily.
- the semifinished product can be heated either as a whole or merely locally, for example in the region of the at least one predetermined folding line.
- the invention also relates to a protective device for a motor-vehicle interior, having at least one winding shaft and at least one flexible sheet-like structure, which is retained on the winding shaft such that it can be wound up thereon and unwound therefrom and which can be displaced between an angled, protective position and a wound-up, stowage position.
- the object on which the invention is based is achieved, as far as the protective device is concerned, in that a housing according to the above description is provided for accommodating the winding shaft and the wound-up flexible sheet-like structure.
- the protective device is preferably designed in the form of a loading-space cover or of a loading-space partition net.
- the protective device it is possible for the protective device to be designed in the form of a sunshade and to be provided for the purpose of shading a vehicle-window surface.
- FIG. 2 shows a schematic perspective view of an exploded illustration of the protective device according to FIG. 1 ,
- FIG. 4 shows an enlarged illustration of a side view of the panel-like semifinished product according to FIG. 3 .
- FIG. 5 shows a schematic perspective illustration—in the same viewing direction as FIG. 3 —of a housing profile of the protective device according to FIGS. 1 and 2 , said housing profile being manufactured from the semifinished product according to FIGS. 3 and 4 ,
- FIG. 6 shows an enlarged illustration of a side view of the housing profile according to FIG. 5 .
- FIG. 7 shows a simplified illustration of a block diagram of an embodiment of a method according to the invention for producing the housing of the protective device according to FIGS. 1 and 2 .
- FIGS. 1 and 2 show a protective device 1 in the form of a cover for a loading space of a station wagon.
- the protective device 1 has a winding shaft 2 and a flexible sheet-like structure 3 in the form of a roller-blind web, which is retained on the winding shaft 2 at one end such that it can be wound up thereon and unwound therefrom.
- the flexible sheet-like structure 3 is illustrated, both in FIG. 1 and in FIG. 2 , in a wound-up state, which can also be referred to as the stowage position.
- the protective device 1 has a housing 4 with a housing profile 5 , which extends along a longitudinal direction L.
- the winding shaft 2 is arranged in the accommodating space A and, at each end, is mounted in a rotatable manner on a bearing element 8 of the housing 4 .
- the bearing elements 8 here are fitted into a respective end opening 9 of the housing profile 5 and are joined together therewith in a manner which is known in principle.
- the housing 4 has end caps 10 , which are arranged at the ends of the housing profile 5 .
- the end caps 10 are each fitted onto the ends of the housing profile 5 , as seen in the longitudinal direction L.
- the flexible sheet-like structure 3 here is displaced through the profile opening 7 .
- the flexible sheet-like structure In the functional position, the flexible sheet-like structure is opened out in an essentially planar state, in a manner which is known in principle.
- the winding shaft 2 is assigned a winding spring 12 .
- the winding spring 12 has one end secured to the winding shaft 2 and the other end secured to the right-hand bearing element 8 —as seen in relation to the plane of the drawing in FIG. 2 .
- the winding spring 12 is prestressed and gives rise to a torque which acts in the winding-up direction around the axis of rotation of the winding shaft 2 .
- This torque serves to wind up the flexible sheet-like structure 3 .
- the housing profile 5 is formed from a panel-like semifinished product 13 which is manufactured from a plastic K and—in a ready-for-use state ( FIGS. 1, 2, 5, 6 )—is angled along at least one predetermined folding line 14 , which extends in the longitudinal direction L, in order for the angular profile cross section 6 to be formed.
- the panel-like semifinished product 13 is flat and has a rectangular elongate basic shape. A length to width ratio here is approximately 10:1.
- the panel-like semifinished product has three longitudinally extending predetermined folding lines 14 , which are oriented parallel to one another. In order for the housing profile 5 to be formed, starting from the configuration which can be seen with reference to FIGS. 3 and 4 , the semifinished product 13 is angled along the predetermined folding lines 14 .
- the profile cross section 6 here has an approximately rectangular basic shape, and therefore the semifinished product 13 is angled in each case approximately at right angles along the predetermined folding lines 14 .
- the profile cross section 6 here is in the form of a box in the manner of a slotted, rectangular hollow profile. This configuration is not imperative.
- the semifinished product 13 can be angled merely along one predetermined folding line 14 . This gives rise to an L-shaped basic shape of the profile cross section 6 .
- the semifinished product 13 can be angled along two predetermined folding lines 14 . This gives rise to a C-shaped or U-shaped basic shape of the profile cross section 6 .
- the predetermined folding lines 14 are each designed in the form of a depression 14 which is prefabricated on the semifinished product 13 . These depressions 14 are formed on the semifinished product 13 in a manner which will be described in more detail.
- the depressions 14 here extend in a continuous manner over an entire length of the semifinished product 13 , and therefore over an entire length of the housing profile 5 . In an embodiment which is not illustrated, the depressions 14 can be interrupted in some regions.
- the predetermined folding lines or depressions 14 provide for a simplified shaping of the semifinished product 13 , and therefor the latter can be angled through 90° in a geometrically defined manner, and with the reduced amount of force being applied, in order for the housing body 5 to be formed.
- the depressions 14 each form a weakening in the semifinished product 13 .
- the semifinished product 13 folds in a defined manner, under a corresponding bending load, in the region of the predetermined folding lines.
- the bending load is clearly shown by way of the moment arrow in FIG. 4 .
- a first profile-wall portion 15 of the semifinished product 13 is angled upward through approximately 90° in relation to a second profile-wall portion 16 .
- a third profile-wall portion 17 is angled upward through approximately 90°, in the opposite direction, relative to the second profile-wall portion 16 .
- a fourth profile-wall portion 18 is displaced in the process together with the third profile-wall portion 17 .
- the fourth profile-wall portion 18 is then angled relative to the third profile-wall portion 17 under the action of a corresponding bending load, this giving rise to the configuration of the profile cross section 6 which can be seen with reference to FIG. 6 and/or the configuration of the housing profile 5 which can be seen with reference to FIG. 5 .
- the depressions 14 are directed toward the accommodating space A and, as a result of the above-described deformation of the semifinished product 13 , are, as it were, folded together.
- the depressions 14 here ensure correctly angled shaping of the profile cross section 6 , since excess material in the corner regions of the profile cross section 6 is avoided.
- the profile opening 7 is formed here between ends 19 , 20 of the panel-like semifinished product 13 which are angled in relation to one another. In the non-angled configuration of the semifinished product 13 , the ends 19 , 20 are arranged opposite one another in a direction perpendicular to the longitudinal direction L ( FIGS. 3 and 4 ).
- the housing profile 5 here, and therefore the semifinished product 13 has a layered construction with a plurality of different material layers 21 , 22 , 23 .
- the material layers 21 , 22 , 23 here are not illustrated to scale and can be seen, in particular with reference to FIG. 4 , merely in a schematically highly simplified form.
- a first of the material layers here is a load-bearing carrying-structure layer 21 .
- the carrying-structure layer 21 is manufactured from the plastic K and provides the housing profile 5 with strength and mechanical stability.
- the plastic K selected here is a glass-fiber-reinforced polypropylene.
- the further material layers 22 , 23 are arranged on either side of the carrying-structure layer 21 , as seen in the thickness direction of the layered construction, and are fixed to said carrying-structure layer in the manner which will be described in more detail.
- One of the material layers is a damping layer 22 .
- the damping layer 22 here is manufactured from a felt and, in the configuration which can be seen with reference to FIGS. 5 and 6 , is arranged on the inside.
- the damping layer 22 therefore forms an inner surface of the housing profile 5 , said inner surface being directed toward the accommodating space A.
- a further material layer here is a covering layer 23 , which is manufactured from a covering material (not referred to in any more detail).
- the covering layer 23 is arranged on a flat side of the carrying-structure layer 21 , said flat side being directed away from the damping layer 22 , and forms an outer surface of the housing profile 5 .
- the covering material here is consistent with a covering material (not illustrated specifically) of the motor-vehicle interior and can be, for example, a textile padding material, a leather or the like.
- the panel-like semifinished product 13 here is produced by means of compression molding.
- Compression molding is a method which is known, in principle, in the field of plastics technology and engineering for the purpose of producing planar or slightly curved components on plastics.
- Both the layered construction with the material layers 21 , 22 , 23 and the predetermined folding lines in the form of the depressions 14 are formed here directly during the compression molding of the semifinished product 13 . This provides for particularly straightforward and cost-effective manufacturing of the semifinished product 13 , and therefore of the housing profile 5 .
- a method for producing the housing 4 is illustrated schematically, in highly simplified form, with reference to FIG. 7 .
- the panel-like semifinished product 13 which is manufactured from plastic, is angled along at least one—in the present case along three—predetermined folding lines 14 .
- the semifinished product 13 is heated in a step b), which precedes the step a) in time. While the semifinished product 13 is being heated in step b), it is softened to become flexible at least in the region of the predetermined folding lines 14 , and therefore the angling of step a) can take place with a reduced amount of force being applied.
- step c) which precedes the heating operation of step b) and the angling operation of step a) in time, the panel-like semifinished product 13 is formed by virtue of at least the plastic K being subjected to compression molding, wherein, in the present case, the predetermined folding lines in the form of the depressions 14 are formed at the same time.
- the step c) here, in addition, provides for at least one of the further material layers 22 , 23 to be subjected to compression molding together with the plastic K.
